The data below shows the number of hours a week in average group of students spend volunteering for community service projects what is a cumulative frequency table that represents the data. 4, 5, 10, 21, 6, 2, 9, 8, 12, 15, 8, 14, 6, 4, 6, 11, 3, 2, 9, 16, 22, 23

The correct option is D.

Step-by-step explanation:

The given data set is

4, 5, 10, 21, 6, 2, 9, 8, 12, 15, 8, 14, 6, 4, 6, 11, 3, 2, 9, 16, 22, 23

A running total of the frequencies is called Cumulative frequency.

Hours          data                  frequency       cumulative frequency      

0-4            4,2,4,3,2                   5                         5+0=5

5-9            5,6,9,8,8,6,6,9         8                         5+8=13

10-14         10,12,14,11                  4                         13+4=17

15-19          15,16                        2                          17+2=19

20-24        21,22,23                  3                          19+3=22

Therefore the correct option is D.
